The cancel_or_refund_on_terminal_response contains a receipts_strct.
The parsed_result, the result returned by the library (lib_result) or terminal (ped_result), is passed in the response_header of receipts_strct.
Check the ped_result and lib_result for the results of processing the request. As this request is not processed on the PSP, no results will be returned in psp_result.
